To freely control the temperature and pressure, the fuel must be diluted with a non-combustible gas. This can be added either before or after ignition, doing so before ignition makes it a lot easier to predict, doing so after ignition is more of an art than a science (it depends on how the furnace is built and how fast the operator can work). The method prefered here is to add the non-combustible gas before ignition. | To freely control the temperature and pressure, the fuel must be diluted with a non-combustible gas.

*The temperature should now be the same as the calculated T(mix) value, unless there was warming or cooling of the gases during the mixing process (in that case, the fuel-dilutant mix has slightly too much or too little dilutant in it, use the tablet to check the ratio of H2 or O2) | *The temperature should now be the same as the calculated T(mix) value, unless there was warming or cooling of the gases during the mixing process (in that case, the fuel-dilutant mix has slightly too much or too little dilutant in it, use the tablet to check the ratio of H2 or O2) | ||
| − | + | The correct fuel mix can be double checked with the following equations. Use the tablet and compare the mol% with these numbers. | |
| − | + | *ratio(O2) = ratio(fuel)/3 (use this one when there is an excess of H2) | |
| − | Use the tablet | + | *ratio(H2) = ratio(fuel)*2/3 (use this one when there is an excess of O2) |
